A Smart card-based service providing system and method, in which a service application uses resources of a common application and which can easily cope with an addition of a service application into the Smart card and thereby efficiently utilize valuable resources of the Smart card, is provided. A management application specially designed for access control is installed in the Smart card to solely manage access management information. A management of or a decision on an access right is not performed by the service application or the common application but by the management application. When a new application is added to the Smart card, the service provider device receives a permission to update access management information beforehand from the card issuer device and, based on the permission, updates the access management information.
